Determine the AER – Air Exchange Rate from Table 1 that best fits your application needs.
Determine the total cubic feet of your plant work area
Total cubic feet = L x W x H (maximum height 20’)
L = length of your workspace (feet)
W = width of your workspace (feet)
H = height of your ceiling in the workspace (feet)
Note - we use dimensions only to 20 feet as smoke, dust and fumes will stratify well below this height. Example: 24 ft ceiling height—20 ft.
Divide the total cubic feet by the AER determined in Step 1.
Divide this total by the CFM of the unit you prefer to use.
T-3000 is 3000 CFM
T-3500 is 3500 CFM
T-4500 is 4500 CFM
T-6000 is 6000 CFM
T-7500 is 7500 CFM
Workspace is 100’ long X 60’ wide X 18’ tall
Total cubic feet is: 100 X 60 X 18 = 108,000 cubic feet
Medium use 5 as the AER (air exchange rate)
(from Table 1) 108,000/ 5 = 21,600
Assume using a T-3500 (3500 CFM unit)
21,600/3500 = 6.17 or 6 units to handle the application.
Determine best location or placement for units.
Our qualified staff is always available to help you determine CFM requirement, placement and then final selection of the units that will provide you the best "cost of ownership" in regards to electrical consumption and filter service costs. Contact Sales @ (877) 624-3247
